PID Parameters
Available in
ECA06 ECA60 ECA600 EMA60 The PID parameters are defined by three parameters:
X X X -
K = controller gain, TI = integral time, TD = derivative time.
Three sets of these parameters are used to facilitate Gain Scheduling as described
below. If the TI parameters are set to Off the Offset parameter is activated. When
TI has a value other than Off the Offset parameter is not used.
Table 99
Note: When Gain Scheduling is disabled and the parameter TI is set to Off, the
Offset parameter is activated. When the control deviation is 0, the controller
output signal is equal to the value of the Offset parameter.
The control parameters should be commissioned via the Autotuner function on
installation. However the parameters can also be set manually.
The ECA06 has only one set of PID parameters – K1, TI1 and TD1.
